  • Web cleaning device for removing contaminants from a moving surface in a printer apparatus
    Patent number: 6195527
    Abstract: A web cleaning device for cleaning contaminants from a moving surface in a printer apparatus. The cleaning device includes a nesting structure having a longitudinally extending internal surface for supporting a coil of a web fabric extending in a longitudinal direction and an external surface located opposite to the internal surface. A lip member forms a part of the nesting structure and is located adjacent a pay out end of the coil. The pay out end of the coil is wrapped about the lip member and further wrapped about the external surface of the nesting structure. The web fabric is also wound about a take-up spindle that is spaced from the coil. A portion of the web fabric from the pay out end of the coil to the external surface of the nesting structure provides a hairpin type curvature to the path of the web fabric to reduce tendency of the web fabric to bind during pay out of the web fabric from the pay out end of the coil.
